Tower Shield (5e Equipment)

From D&D Wiki

This massive shield is used frequently in organized armies for its effectiveness at protecting soldiers and aiding in the formation of lines.

While you are holding a tower shield:

You have disadvantage on attack rolls.

You have half cover.

You can spend an amount of movement equal to half your speed to have three-quarters cover until the start of your next turn. If you do this, then when you are an obstacle to a target [PHB. p. 196] you grant three-quarters cover instead of half cover.
